碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 93 === This thesis proposes the novel design method for compliant mechanisms. The difference between compliant mechanisms and traditional mechanisms is the characteristic flexibility of the compliant mechanisms. When we apply different loads such as forces or displacements in the mechanisms system, we use the flexibility of compliant mechanisms to generate expectably related effects to consummate our special functional purposes. This study utilizes the multi-input method to obtain larger output force and displacement. The design domain is made by the Ground Structure Parameterization of the topology optimum. The goal is not only to find the most efficient method in computing the optimal topology but also to obtain the sharpest topology layout. The main purpose of topology optimal design is to make a general shape of mechanical components which has light weight and can satisfied the design requirements.　In addition, the shape obtained from topology optimum design can be taken as the initial shape of shape optimization. The result is better than traditional shape optimum design method. This study combines with the topology optimum compliant mechanism and the piezoelectric microactuator to design a microgripper and analyze the effects for results with different parameters in topology optimization.
